Abstract
Method and apparatus for module design in a PLD is described. In one example, a PLD includes a reconfigurable module, a static module, and at least one logic interface macro. The reconfigurable module includes a signal interface and is configured for active partial reconfiguration. The static module includes a signal interface. Each logic interface macro includes first pins coupled to the signal interface of the reconfigurable module and second pins coupled to the signal interface of the static module. The first pins and the second pins are disposed in an implementation area of the reconfigurable module. In one embodiment, each logic interface macro includes a slice of a configurable logic block (CLB). In some embodiments, each logic interface macro is implemented using another type of logic block, such as a block RAM and/or multiplier block.
